Title:

DISTRIBUTED ROUTING METHOD AND APPARATUS BASED ON OPEN VSWITCH KERNEL STATE FLOW TABLES IN OVERLAY NETWORK

Document Type and Number:

WIPO Patent Application WO/2021/139269

Kind Code:

A1

Abstract:

The present application relates to the field of artificial intelligence and discloses a distributed routing method and apparatus based on open vSwitch kernel state flow tables in an overlay network. The method comprises: when establishing virtual machines in a virtual private cloud of an overlay network, synchronously configuring flow tables separately for four different intercommunication types in the virtual private cloud; maintaining the flow tables in a host kernel during the life cycles of the virtual machines; the four intercommunication types include the type of intercommunication between different virtual machines in a same virtual private cloud, the type of intercommunication between virtual machines in different virtual private clouds, the type of Internet access by virtual machines in a virtual private cloud, and the type of data center common installation access by virtual machines in a virtual private cloud; the flow tables are Open vSwitch kernel state flow tables. The present application configures flow tables separately for four intercommunication types, and the configured flow tables all use kernel state flow tables, thereby avoiding performance degradation due to a large number of upcalls. The configured flow tables accompany the virtual machines for the whole life cycle, thereby providing stable and reliable flow table-based statistics.
